I'm having a problem burning CDs in iTunes....I put the songs in a playlist, click burn (burning as an audio cd), and my computer (Asus W7J laptop) goes through the motions of burning a cd. CD drive spools up, iTunes shows the progress of each song being burned, then the disc is finalized. If I look at the disc I can see that it has been burned (I can see the color difference), but there's nothing on the disc. My computer can't see anything, my other computer can't, my car won't play it. What's wrong here? thanks!
